From real-world success stories, there are two fascinating real-world examples showcasing the versatility and value of Amazon S3:

• Nasdaq’s Data Archival: Nasdaq, a prominent player in the financial sector, efficiently stores seven years’ worth of crucial data using the S3 Glacier share service. This service, akin to Amazon S3’s archival feature, ensures secure and cost-effective long-term data preservation for Nasdaq.
• Sysco’s Data Analytics: Sysco, a leading food service distribution company, harnesses the power of Amazon S3 to run sophisticated data analytics. Through this process, Sysco gains invaluable business insights, empowering them to make informed decisions and enhance operational efficiency.

These real-world use cases exemplify how Amazon S3 caters to diverse needs, from data archival for enterprises like Nasdaq to empowering data-driven decision-making for companies like Sysco. By leveraging Amazon S3’s capabilities, organizations can unlock new possibilities and stay at the forefront of their respective industries.

Amazon S3 — Buckets

Amazon S3 stores files into buckets and buckets can be seen as top-level directories. The files in these S3 buckets are called objects. There are naming rules for S3 buckets. You don’t have to remember it, but it’s good to know.

The following rules apply for naming buckets in Amazon S3:

1. Bucket names should be between 3 and 63 characters long.
2. They can consist only of lowercase letters, numbers, dots (.), and hyphens (-).
3. Bucket names must begin and end with a letter or number.
4. Avoid using two adjacent periods in bucket names.
5. Refrain from formatting bucket names as IP addresses, for example, 192.168.5.4.
6. Steer clear of starting bucket names with the prefix “xn — “.
7. Also, don’t begin bucket names with “sthree-” and “sthree-configurator” prefixes.
8. Bucket names must not end with the suffix “-s3alias” as it’s reserved for access point alias names.
9. Similarly, avoid using the suffix “ — ol-s3” as it’s reserved for Object Lambda Access Point alias names.
10. Ensure bucket names are unique across all AWS accounts within a partition, where AWS currently has three partitions: aws (Standard Regions), aws-cn (China Regions), and aws-us-gov (AWS GovCloud (US)).
11. Once a bucket is created, its name cannot be used by another AWS account in the same partition until it’s deleted.
12. For buckets used with Amazon S3 Transfer Acceleration, dots (.) in their names should be avoided, except for those intended solely for static website hosting. The presence of dots affects virtual-host-style addressing over HTTPS, unless you perform your own certificate validation. This limitation, however, doesn’t apply to buckets used solely for static website hosting, as they are available over HTTP.

Amazon S3 — Objects

Amazon S3 objects essentially represent files within the storage system.

S3 Object keys

Each object is uniquely identified by its key, which denotes the full path of the file within the S3 bucket.

For instance, consider the object with the key:

In this example, my-bucket serves as the top-level directory, and the key for the text file is simply my_file.txt.

Now, if we wish to organize our files into nested folders, the key would reflect the complete path:

In this case, the key would be my_folder/my_subfolder/my_file.txt, where my_folder/my_subfolder/ forms the “prefix,” and my_file.txt represents the “object name.”

It’s important to understand that while Amazon S3 appears to have directories when viewed through the console UI, it doesn’t strictly adhere to traditional folder structures. In reality, everything within Amazon S3 is treated as an object, and keys are utilized to manage and locate these objects effectively.

By grasping the concept of Amazon S3 object keys, users can efficiently organize and retrieve their data, creating a seamless and reliable storage experience.

S3 Object size

When working with Amazon S3, it’s essential to be aware of the size limitations for individual objects, which are essentially files stored in the system. The maximum size allowed for a single object is an impressive 5 TB, offering ample storage capacity for large-scale data.

However, when uploading objects greater than 100 MB in size, it is recommended to leverage the multipart upload capability. This feature enables the efficient transfer of sizable files by breaking them into smaller parts, enhancing reliability and performance. Each part of the multipart upload can be up to 5 GB in size, ensuring a manageable and seamless process.

To illustrate, let’s consider a scenario where you have a massive file of 5 TB. In this case, you must utilize the multipart upload functionality, which will automatically divide the file into multiple parts, each with a maximum size of 5 GB. Consequently, this process will create at least 1024 parts, allowing for efficient and successful uploading of the entire 5 TB file.

By understanding and applying these size considerations, users can optimize their Amazon S3 experience, efficiently managing and transferring files of varying sizes with ease and confidence.

S3 Object metadata

The object also possesses a powerful feature known as metadata. Metadata comprises a collection of key and value pairs, which can be automatically set by the system or intentionally assigned by users. This metadata serves as valuable information about the file, offering insights into specific elements related to the object.

Furthermore, users can leverage up to 10 Unicode key/value pairs, referred to as tags. These tags play a crucial role in enhancing security measures and managing object lifecycles effectively.

In addition to metadata and tags, it’s essential to note that each object is equipped with a Version ID, provided that versioning is enabled. This Version ID serves as a unique identifier for the object, facilitating easy tracking and management of various versions of the same file.

By utilizing these powerful features, users can add meaningful context to their objects, enhance security measures, and streamline lifecycle management effectively within the Amazon S3 environment.

Phew, we’ve covered a ton of ground and learned so much about introduction to Amazon S3!🌟

Remember, when you dive into Amazon S3, buckets are your top-level directories, and objects are the actual files. Get creative with object keys, organize your data like a champ, and don’t forget those cool metadata and tags! It’s all about making your storage experience seamless and reliable!
